Technique With the patient in the supine position the femoral artery is located within the inguinal crease discount precose 25 mg without prescription diet diabetes yang baik. Using a nerve stimulation technique proven 25mg precose diabetic diet lunch ideas, the needle is guided in a lateral to medial direction to evoke patellar movement or quadriceps muscle twitch order precose 50mg online diabetes type 1 high blood sugar. Thigh twitching is commonly noted indicating stimulation of the sartorius muscle generic precose 50mg overnight delivery blood glucose dangerous levels, which should not be misinterpreted for quadriceps stimulation. The femoral vein, artery, and nerve can be visualized from medial to lateral when Regional Anesthesia in Children 35 Fig. An out-of-plane or in-plane approach may be undertaken to direct needle placement to femoral nerve and circumferentially surround it with local anesthetic. Complications Possible complications arise from the proximity of the femoral nerve in relation to the artery and vein. Unintentional vessel puncture and hematoma formation are potential complications as are nerve injury and infection at the site of needle insertion. Associated risks of indwelling catheter placement include that of infection, prolonged numbness, as well as catheter kinking, dislodgment and disconnection. Sciatic Nerve Blocks Anatomy and Indications Innervation of the posterior thigh and all but the medial part of the leg distal to the knee is provided for by the the sciatic nerve which is formed by nerve roots L4 to S3. The sciatic nerve continues to the posterior popliteal fossa then bifurcates to form the tibial and common peroneal nerves. In children, various locations of the sciatic nerve can be blocked via the subgluteal, anterior thigh, or popliteal approach. Successful prolonged analgesia with a continuous sciatic nerve blockade has been described. Pain management for ankle and major foot surgery in children can be accomplished by continuous sciatic nerve block. Fewer adverse effects have been demonstrated with use of continuous sciatic nerve blockade 36 Yearbook of Anesthesiology-6 as compared to epidural anesthesia in children undergoing major ankle and foot surgery. Technique With the subgluteal approach to the sciatic nerve block, the patient is placed in the lateral decubitus position with the hip and knee flexed. The nerve can be visualized between the greater trochanter and the ischial tuberosity deep to the gluteus maximus muscle with the use of ultrasonography (Fig. Success with this block has been described with both an in-plane and out-of-plane approach. In performing this block, nerve stimulation may be used alone or in combination with ultrasound. Successful continuous sciatic nerve blockade with catheter placement has been described in children. A sciatic nerve block via the anterior approach may be accomplished with use of either nerve stimulation and/or ultrasonography. The probe is positioned below the inguinal crease and the sciatic nerve is seen deep and medial to the femur. In older children as the sciatic nerve is at an increased depth, this approach may be technically challenging. The popliteal artery is easily visualized and adjacent to the artery is the sciatic nerve. Distally the common peroneal and tibial nerves can be seen diverging from the sciatic nerve and may be blocked individually. One may elicit calf, foot, or toe twitches at this location with the use of nerve stimulation. Of note, the popliteal fossa approach using the same technique may be performed but with the child in supine position with the hip and knee flexed. When children undergoing major foot and ankle surgery with sciatic nerve blockade were compared to those with continuous epidural block, both techniques were associated with good postoperative analgesia. However, less urinary retention, less discontinuation of local anesthetic infusion, and less nausea and vomiting were demonstrated in children with continuous popliteal nerve catheters. Saphenous Nerve Block Anatomy and Indications The saphenous nerve provides innervation to the knee as well as the medial portion of the leg below the knee. It is a branch of the femoral nerve, running adjacent to the sartorius muscle traveling within the adductor canal before continuing to the medial aspect of the knee. Blocking the saphenous nerve proximally allows for analgesia of the anterior knee while blocking it distally provides analgesia soley to the medial aspect of the lower extremity. The sartorius muscle is identified and juxtaposed to this is the saphenous nerve (Fig. The needle is directed using this technique to the saphenous nerve, where the local anesthetic is deposited. The saphenous nerve is lying juxtaposed with sartorius muscle 38 Yearbook of Anesthesiology-6 Complications Saphenous nerve blockade complications include infection, injury to the nerve, and hematoma formation from inadvertent arterial puncture. The efficacy and safety of these various techniques will likely help ease the transition to early ambulation with enhanced pain management without the use of opioids and their side effect profile. Regional anesthesia in children continues to make advancements with the use of ultrasound in the perioperative setting including the increased availability of point of care ultrasonography. The frequency with which peripheral regional anesthesia is being utilized is persistently growing in the pediatric population. While some studies suggest utilization of ultrasonography may decrease the least possible dose of local anesthetic required for successful blockade, additional studies are necessary to elucidate the complete risks and benefits of completing peripheral regional anesthesia. There remains an important role in regional anesthesia for nerve stimulation and clinicians may choose either approach. Data available demonstrates particular benefits to the use of both ultrasound guidance and nerve stimulation in nerve blocks. Whichever technique is chosen, all means should be used to advance regional anesthesia in children with the ultimate goal of improving the perioperative experience for children.
